APPARATUS FOR TREATING GRAIN.

Specification of Letters Patent.

Patented June '7, 1910.

Application filed December 23, 1909. Serial No. 584,734.

"Be it known that I, Ezekiel. B. Cox, a citizen of the United States, residing at Newtown, Pennsylvania, have invented certain new and useful Improvements in Apparatus for Treating Grain, of which the ollowing is a specification.

My invention relates to an im roved apparatus for ridding grain of al material which is softer than the grain, although it may beof such size and weight as to be incapable of separation by the ordinary methods of screening or scouring.

By my improved apparatus, I subject the grams to agrmding action, which, while of such a character that it will not injure the good and hard kernels of the grain, will grind up or-pulverize all garlic and bugeaten-or moth-eaten kernels, reducing them to such a condition that they are readily separated by the ordinary screening or scouring machines.

The invention includes the novel features of construction and arrangement and combination of parts of the apparatus hereinafter described and particularly set forth in the appended claims. I

A' machine constructed in accordance with my invention is illustrated in th panying drawings, in which Figure 1 is a sectional elevation; Fig. 2 an enlarged viewof the cut off plate and Fig. 4 is an ening.

Referring by reference characters to these drawings, the numeral 1 designates the uprights of a main upright frame connected at bottom and top by'the horizontal members 2 and 3, which, in turn, sup ort the cross bars 4 and 5, the lower one 0 which carries the step bearing for the lower endof the vertical shaft 6, which carries the rotary parts of. the machine as hereinafter described. The shaft 6 is journaled at its up er end in a bearing 7 carried by the bar 5. gupported on suitable uprights 8 within the frame members is a casing 9 which. has leading from its lower side a spout 9 which discharges upon a screen 10 carried by a screen frame 10" mounted upon vertically disposed flat springs 11 and receiving a longitudinal reciprocating motion through a bar 1-2 connected to a strap 13 working upon an eccentrio 14 on the shaft 6, rotary motion bemg accomlarged cross sectional view through the casimparted to the shaft through a driven pulley 15 to which motion is imparted from any suitable source of power. The casing 9 is providedfwith a cover plate 16, whichis provided with a plurality of openings 16, and above this cover late is rotatably mounted a cut-ofl' plate 1 which is provided with corresponding holes 17 and a handle 18, by means of which it may be rotated-to vary the size of the openings leading into the casing. Within the casing is located. a revolving scraper arm 19 which has its hub securely fastened to the shaft 6 by any suitable means-such as a set screw 19, and it will be seen that as this scraper blade r0- tates or revolves within the casing, it will cause any material which has been delivered through the spout. Above the casing are mounted a plurality of easing rings 20,

into the casing and rests upon the bottom 3 thereof to be carried around and discharged which are preferably of octagonal'cross secq .5 tion. These are mounted the one above the other, and are provided wlth sets of pro-v jecting lugs 20, which are on ged by the ing to the character of the formed. j g

The shaft 6ycarries within the casm a work to be perdisk 24 supported upon an adjustable co ar '25, which may be secured 1n any suitable position by a set screw 26, and above this disk 24 are arranged in alternatlon dISlIS' orv plates 27 rovlded with serrated or toothed edges, an other disks or rings 28 provided with projecting pins 28.

The cover late is provlded w1th the open,- ing 22 for t e admission of thegram, and

the shaft 6 carries a rotary plate or frame 32 provided with upwardly projecting distributer teeth 30, which may staggered relation to downwardly proyectingjteeth 31 carried by bars 29 secured to the under side of the cover plate.

From the above description it is thought that the operation of the a paratus will be obvious, but it may be brie y stated as follows: The grain to be treated, such, for mstance, as wheat, is fed in through the mlet opening, and distributed by the revolving vertically disposed clamping r0 s21. Upon the topmost ring is located a cover plate 22.

e arranged in 85 which may be built up to any height aoco'rdteeth on the plate 29, and thence it passes I in the collecting chamber, substantially as downward upon the topmost plate 27, and

is thrown outward by centrifugal action against the rings, and thence passes down between the revolving teeth and the rin being acted upon by the said teeth and ti e pins or projections on the disk, which results in grinding up or pulverizing all softer materials, such as arlic or insect-eaten grain, while the bar sound grains remain unaffected, and are delivered from the machine upon the screen 10 in a whole condition, when they are separated from the pulverized material. By means of the handle 18, the discharge openings in the plate 16 may be more or less closed to retain the grain within the casing rings for a sufficient length of time to secure the requisite grinding action, which length of time is readily determined by experience.

Having thus described my invention what I claim is Y 1. In combination a stationary cylindrical casing having a plurality of alternate grooves and ridges on the interior and arotary grinding device within the casin comprising a plurality of superimpose disks having serrated edges and other disks alternately arranged with respect to the other disks and having pins projecting from their edges, and aninlet to and discharge from said casing.

2. In combination a collecting casing or chamber, a casing surmounting said collectthe casing, a

ing chamber and composed of a plurality of rings having beveled edges and superimposed upon each other, a shaft journaled in rinding device consisting of superimposed isks mounted upon said shaft and having alternately teeth and projecting pins coacting with the inner surface of said rings, a cutoff plate controlling the admission of rain to the collecting casing, a discharge om the collecting casing, and a rotary scraper blade carried by the shaft withdescribed.

3. In combination a suitable frame, a collecting casing supported therein above the bottom of the frame and-having a suitable discharge outlet at one side, a plurality of rings superimposed above said collecting casing and constituting a grinding casing, a shaft journaled vertically in the frame and passing through said collecting and grindin casing, a scraper plate earned by the sha t within the collecting casing, a plurality of serrated disks carried by the shaft within the grinding casing, a cut-off device for controlling the communication between said casings, and a feed opening for the grain at the upper end of said grinding casing, substantially as described.

4. In combination a suitable frame, a collecting casing supported therein above the bottom of the frame and having a suitable Y discharge outlet 'at one side, av plurality of rings superimposed, above said collecting casing and constituting a grinding casing, a shaft journaled vertically in the frame and assing through said collecting and grinding casing, a scraper plate carried by the shaft within the collecting casing, a plurality of serrated disks carried by the shaft within the grinding casing, a cut-ofi' device adapted to control the communication between said casings, and a feed 0 ening for the grain at the upper end of sai grinding casing, a screen adapted to receive the discharge from the collecting E casing, and means whereby said screen receives reciprocatin motion from the vertical shaft, substantially as described.

'In testimony whereof, I afiix my signature in presence of two witnesses.
